Application filed December 30, 19.12. Serial no. 33,250.

To all whom it may concern:

Be it known that I, RICARDO, .Bnasonnz Duran, a'oitizenof the Republic of Mexico, and a resident of Torreon, in the State Of Coahuila, Mexico, have invented a new and Improved Support for Electric Wires, of which the following is a full, clear, and exact description. I

My invention has forits object to provide a support for electric wires, which makes the use of an auxiliary supporting cable un-.

necessary, while, at thesame time, doing away with, all danger from broken or fallen electric wires.

Briefly my invention consists of wire supports, with pivoted conducting arms, to which the terminals of the wire sections are secured, the conducting arms being held in electrical communication with central cone ductors, by the wire sections, when the wires are in normal position. However, when a wire section is broken or falls, the weight of the wire will move the arm out of electrical communication with the central conductor, so that the fallen Wire Will not endanger pedestrians.

Another object of the invention is to prevent the wearing of the wire sections at their supports.

Still other objects of the invention will appear in the following complete specification, in which the preferred form of the invention is disclosed. V

In the drawings similar characters of reference indicate corresponding parts in all the views, in which Figure 1 is a side elevation of my invention, showing parts in section; Fig. 2 is a side elevation, similar to that shown in Fig. 1, but with the conducting arms moved so I that there is no longer an electrical communication with the conductor of the central wire support; Fig. 3 is a plan view of Fig. 1; Fig. 4 is a sectional view on the line 2-4 of Fig. 1; and Fig. 5 is a sectional view on the line 5-5 of Fig.1.

By referring to the drawings it will be seen that a non-conducting member 5 is provided, to the bottom of which there is secured a conducting shoe 6, which is spaced from the ends 7 of the non-conducting member 5, and extending therefrom there are arms 8, these arms 8 being provided in two pairs, a lever 9 being fulcrumed between each pair of arms. These levers 9 are constructed of conducting material, and they re provid d with caps. which ser e as sw tch movers and which ar adapted t enea eth projecting wit h. niece ll. on

he co ducting member 2, s ured to. the

latentegl iaia.

sp. oft e n n-cond ct ng membe 5, at its;

opposite ends. The co.nducl; gm. mber 2 ar eenne ed elec rica ly w h th cond cts shoe firbv 'me ns'ofhe i sula ed conducting wires 13, which are secured to the nduct ng member- .1 and the, conduc in h e 2 th usto ary mar ner. It ill herefore be. see th t. the. lwe st are; r

the conducting shoe 6, and'then through the other conducting wired?) tothje iother con;

.ducting member 12, and to the other lever 9.

Each of the levers 9 has a groove 15 at its under side, and extending to its free end.

In each of these grooves there is disposeda wire 16, the wire 16 extendingthrough an opening 17 to the top of the arm 14:, the wire 16 being engaged by a screw 18, which meshes in a threaded orifice 19 extending to the opening 17. In this way the wires 16 are secured to the arms l-fllof the levers 9, and as the wires 16 are normally disposed horizontally, as shown in Fig. 1 of the drawings, they serve to hold the levers in such a position that the switch caps 10 engage the switch members 11, so that thecurrent may pass through the right lever 9, and through the parts which have been described, to the left lever 9, to the wires 16 at the left of the wire support. In order to permit the trolley wheel which may engage the wires 16 and the shoe 6. to pass readily from the bottom of one of the levers 9 to the conducting shoe 6, I provide the bottom of the nonconducting member 5 at its opposite ends, with metal shoes 20, which receive the trolleyv wheel as it leaves the bottom of one of the levers 9. and conducts the trolley wheel from one of the levers 9 tothe conducting shoe 6. Secured to the top of the non-conducting member 5 there is a saddle 21, which has a spindle 22, on which is mounted laterally extending arms 23,these laterally exnon-conducting member ,5, and below the saddle 21, these eye members 25 serving as n additional means for. holding thewiresupport in position.

It will be seen by'referring to Fig. 2 of thedrawings, that when a trolley Wheel 26 passes from. one Wire or cable 16, to the other Wire or cable '16, it will not Wear the ters Potent:
